KUALA LUMPUR (Dec 14): Total circulating Bitcoins hit a major milestone on Monday (Dec 13) as 90% of the maximum total supply had been mined.
Citing current data from Blockchain.com, cryptocurrency news portal Cointelegraph said Bitcoins in circulation hit 18.899 million as of Monday, meaning only 10% of the total supply was left to mine.
The total supply of Bitcoins is limited and predefined in the Bitcoin protocol at 21 million, with the mining reward (how Bitcoins are created) decreasing over time.
The Bitcoin reward is divided by two every 210,000 blocks, or approximately four years. Some of the Bitcoins in circulation are believed to be lost forever or unspendable, for example because of lost passwords, wrong output addresses or mistakes in the output scripts.
The number of Bitcoins in circulation is calculated from the theoretical reward defined by the Bitcoin protocol.
Cointelegraph said it will take 119 years from now to complete the Bitcoin mining process due to the rate of producing new Bitcoins being cut by half every four years in a predetermined protocol execution known as Bitcoin halving.
